Congenital bilateral aplasia of the vas deferens (CBAVD), which leads to male infertility, may occur in isolation or as a manifestation of cystic fibrosis. Males with cystic fibrosis are infertile because of abnormal functioning of the vas deferens. The changes that occur in the ducts comprise degenerative obstruction similar to this which is found in excretory glands in cystic fibrosis.
